Abstract:
In this study, the role of varying Sn concentration (x = 0, 1, 2, 3 and 4 wt%) on the microstructure and mechanical properties of Mg-6Zn-0.6Si-xSn alloys has been investigated. The type, distribution and volume fraction of the precipitates have been carried out using both scanning electron microscopy (2D) and X-ray tomography (3D). The Mg2Sn phase appeared after addition of 2 wt% Sn. The increase in the compressive strength of the alloy with increase in Sn addition has been attributed to both precipitation strengthening as well as solid solution strengthening.
